How come a lot of the dyno's I see in SN member's threads the power drops off, well dyno's in general, always have the power drop off. I mean when you spin the engine, you make power, and the faster you spin the more you make. So theoretically the faster the more power, but why is it that the power drops off, I mean i understand the TQ dropping off due to the mathematics and calculation of HP. so why does the power drop off, cam selection? valve float?
